Solution Approach 1:

The patent introduces an intermediary processing system that includes a camera to capture color information, a processor to analyze the captured data, and a reference color storage system. This intermediary system mediates between the uncontrolled lighting environment and the color detection task, compensating for illumination variations through computational processing and comparison with stored reference colors under standardized lighting conditions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the parameter of color representation from direct human perception to quantifiable digital data. By converting color information into numerical values that can be processed and compared computationally, the system overcomes the limitations of human color vision and the effects of varying lighting conditions through mathematical transformations and reference comparisons.

Inventive Principle:

2Ease of operation

If color matching is performed based on human vision characteristics, then the system aligns with human perception, but measurement precision deteriorates due to individual variations in color perception and age-related changes

Engineering Contradiction:

Improvealignment with human color perceptionVSAvoidcolor interpretation consistency

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent creates a standardized reference copy of color information stored in memory, representing colors under controlled lighting conditions. Instead of relying on variable human perception, the system uses these stored reference copies as the authoritative standard for comparison, ensuring consistent and reproducible color matching across different users and conditions.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system performs preliminary action by pre-storing reference color data under standardized lighting conditions before the actual color matching task. This advance preparation of reference standards allows the system to compensate for variations in perception and lighting during operation, ensuring consistent results without requiring real-time calibration for each user.

Inventive Principle:

Solution Approach 1:

The patent replaces the mechanical/optical approach of increasing physical illumination intensity with a computational approach. The system uses image processing algorithms and reference color comparisons to extract accurate color information from images captured under various lighting conditions, eliminating the need to physically increase light intensity to overcome noise thresholds.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
